Celebrate Canada Day with the first installment in our new kettle sour series: Haskap Kettle Sour. This tart and fruity little brew pours a beautiful red like the proud maple leaf on our nation's flag. Haskap's are a little-known berry found mostly in northern climates like Canada, Russia, and Japan, with a flavor that combines the tartness of raspberries with the smooth sweetness of blueberries.
